If f(x) = 2x^2 - 3x + 4, what is f(3)?

Explanation:
Evaluating a polynomial at a specific value means substitute that value for the variable and simplify. For f(x) = 2x^2 - 3x + 4, plug in x = 3: f(3) = 2(3)^2 - 3(3) + 4. Compute: (3)^2 = 9, so 2(9) = 18; -3(3) = -9. Then 18 - 9 + 4 = 13. So f(3) = 13.
